State trooper kills himself after inquiry launched

DEVENS — A 40-year-old state trooper under investigation killed himself Monday in the Hilton Garden Inn after he told people he intended to harm himself, state police said Tuesday.

The trooper, who was not named in a state police news release on the death, was the subject of an investigation that began Sunday. State police said the investigation involved an alleged criminal act that occurred early Sunday morning while he was on duty.

"The trooper was the subject of an investigation, initiated Sunday, into an alleged criminal act that occurred early Sunday morning while he was on duty," state police spokesman David Procopio said in the release.

"Upon initiation of the investigation, his use-of-force equipment, including his service firearm, was confiscated and he was relieved of duty," state police said in the release.

On Monday, the trooper made statements to two people that he was going to harm himself. They contacted state police, who began looking for the trooper. He was found in the hotel room with self-inflicted wounds.

State police said the trooper had been a member of the department since June 2005. They did not disclose his role in the state police or any further details.

According to Trooper Jasinskas' obituary in The Boston Globe, he was in the Marines and the National Guard for 20 years.
